Who invented DST?
New Zealand scientist George Vernon Hudson and British builder William Willett invented DST. In 1895, Hudson presented a paper to the Wellington philosophical society, proposing a 2-hour shift forward in October and a 2-hour shift back in March. There was interest in the idea but it was never followed.
In1905, independently from Hudson, British builder William Willet suggested setting the clocks ahead 20 minutes each of the Sundays in April and switching them back by the same amount on each of the four Sundays in September. a total of 8 times switches per year.
